Attorneys for Apple said Friday the technology company will provide expert testimony at next week’s hearing in its case against the Department of Justice involving the San Bernardino shooter’s iPhone.

Attorneys for Apple said they were surprised to learn of a request late Wednesday by the Department of Justice calling for cross-examination at Tuesday’s hearing, a move they say should have been made weeks ago.

“When two parties disagree, courts hold hearings with witnesses to find out the facts,” said Emily Pierce, spokeswoman for the Justice Departmen in a statement. “That’s how the American justice system works. The dispute will be decided by a judge based on the facts and the law.”

Apple’s manager of user privacy, Erik Neuenschwander, as well as Lisa Ollie, who dealt directly with the FBI during the investigation, will be available for cross examination, attorneys for apple said Friday in a conference call with media.

In his declaration to the court, Neuenschwander said once Apple creates the software requested by the FBI, it would take only minutes for Apple or a “malicious actor with sufficient access” to perform the necessary engineering work to install it on another device of the same model.

The government will make available two FBI agents, Apple said. All the witnesses have provided declarations to the courts, Apple attorney said.

Magistrate Judge Sheri Pym is expected to open the hearing with her own statements.

The Department of Justice is seeking that the technology giant build software that would allow the FBI to unlock the encrypted work-issued iPhone 5C used by San Bernardino mass shooting gunman Syed Rizwan Farook. Farook and his wife, Tashfeen Malik, killed 14 people and wounded 22 others on Dec. 2 at the Inland Regional Center in San Bernardino, in what has been called the deadliest terrorist attack on US soil since 9/11. The couple were killed in a shootout with police hours later.

Apple argues that building the software sought by the FBI will create a “master key” enabling hackers to unlock millions of other iPhones and breach data security of its customers.

Both sides will have about two hours to cross-examine witnesses before oral arguments begin.

In court, attorneys for Apple say they will continue to stress that the All Writs Act is not a “limitless license” for law enforcement to compel third parties to do what the FBI is requesting.
